2608

Model 2608 is an analog I/O module that connects to Ethernet through a 2601 communication module. It has sixteen differential analog inputs and 0, 4 or 8 analog outputs. It is a member of the 2600 series of smart I/O modules.

Common mode voltage range

The CMV range for analog inputs is -10 to +10V for both the 100mV and 10V input ranges.

Visual identification

Is there a visible difference between models 2608-0, -4 and -8?

Yes. Locate integrated circuits U6 and U27 on the circuit board (near analog output connectors), which are populated differently for each model (yes=populated, no=unpopulated):

Model	U6	U27
2608-0	no	no
2608-4	yes	no
2608-8	yes	yes
